A property manager can handle 200 tenants. That’s the industry limit. Why? Because the work scales linearly: matching bank transactions to invoices, chasing late payments, answering tenant questions, coordinating repairs, preparing legal notices, renewing leases. More tenants, more of the same manual work.

With AI, that limit disappears. And both landlords and tenants get a better experience.

About Proper

Eight years in property operations. ~1,000 customers across Denmark, Netherlands, and Germany. We know this industry — the workflows, the pain points, the regulations.

Now we’re making a big move: becoming a full-service property operator. Tenant communication, bookkeeping, coordinating repairs — we handle it. A landlord shouldn’t chase late payments or find a plumber at 10pm. We do it for them.

We’re building an entirely new platform to power this. AI-native from day one. Profitable, real customers, expanding across the Nordics.

Why this is interesting

We’re shipping production software with AI agents as part of the development workflow. Not a side experiment — this is how we build.

Our codebase has custom Claude Code skills. AI writes code, we review it. AI runs tests, we verify. We’re figuring out what it means when your most productive team member isn’t human.

The product side is equally interesting. Property management is perfect for AI: thousands of similar transactions, pattern-based decisions, templated documents. Years of domain knowledge ready to encode into intelligent systems.

The role

You’ll shape the architecture of a platform being built from scratch.

• Work directly with our co-founder
• Own features end-to-end — database to API to UI
• Ship fast — mockups, prototypes, iteration
• Make architectural decisions that scale across the Nordics
• Build AI into core product features

This isn’t a ticket-taker role. We need someone who looks at messy problems and figures out what to build.

Tech stack

TypeScript everywhere.

• Backend: NestJS, PostgreSQL, Drizzle ORM
• Frontend: Next.js, React, TailwindCSS
• Infra: AWS Lambda, CDK, RDS, EventBridge, SQS

TypeScript and AWS experience required. The rest you’ll pick up.

What we’re looking for

• Strong TypeScript/Node.js
• Full-stack (backend + React)
• AWS experience
• Product thinking — understand problems, not just requirements
• Work independently
• Copenhagen-based (on-site)

Big plus: AI experience (prompt engineering, RAG, agents), fintech/proptech background.

Compensation & benefits

• Compensation: 50–65K DKK, depending on experience and demonstrated competencies
• Equity: Employee warrants offering real ownership in the company
• Workspace: Centrally located Copenhagen office
• Perks: Daily lunch included

Why Proper?

Real customers. Brand-new codebase. Small team where your decisions matter.

We’re rebuilding from the ground up with AI as the foundation. If you want to shape property tech at scale and see what software development looks like when AI is a real collaborator — reach out.
